ToaZZ 'whom t may concern.'

:'Benit known that I, vWILLIAM J. IIA,

a citizen;` of the United States, residing at l objects such las purses, knives, Vanity boxes,

coin boxes, or otherwise, metallic or nonmetallic. i

As my invention is peculiarly adapted for attachment on a knife, a further object of i my invention .isto provide in one complete device a key-holder andy a knife.` 4.

A further object of my invention isto provide a key-holding attachment, the outer shell of which is peculiarly adaptedfor surface ornamentation, and they key-retaining device especially simplerofmanufacture and sure in its action. Y

A furtherl object of'my invention is to provide a key-holding attachment adapted for useoneither a metallic orinon-metallic base.v V

These `and suchother objects'of-my inf vention vas may hereinafter appear will be best understood from'a description of the accompanying4 drawings which illustrate one embodiment thereof on -a knife.

In the drawings, F ig, 1 is a perspective View of a knife with myv key-holding attachment secured thereto, the key being partially withdrawn;

. attachment securedto al knife, it is apparent Y v Fig. 2 isa front elevationof the knife, the key-holding attachment being show in section; i

Fig. 8 is an end view of the knife with the key removed; and

Fig, 4 is a perspective view of the flat key-retaining spring. s l

In the'clrawings, wherein like characters of reference indicate like parts throughout,4

1 indicates a knifewith the blades 2 pivotally secured thereto, as usual. The knife 1 is provided with the usual outer shell 3 and bail -4. 'j f Y,

Though I have shown my key-holding that may be readily attached to any object, non-metallic or oth'erwise.-v My keyholding attachment comprises a shell casing 5, the downwardly projecting flanges 6.A

thereof being adapted to be conveniently attached to any object, so as to leave a sheath 16 between lsaid casing 5 and object, a flat key-retaining spring 7,1a key 9 suitablyesevcured toa key handle 10, and preferably a lshell covering 12, providedfwithsimilar downwardly projecting flanges 18, adapted to completely telescope and fit flush against the key'handle 10, the exposed surface of which covering may kbeornamented in similarhfas'hion to the exposed lsurface ofthe outer shell 5 (as shown in Fig. 1).` The key-retaining spring7 is shown in detail in Felice.;

'WILLIAM'.I'. HANNA, or ATTLEBoRo, lvrassnei1trsr'rr'-1s.v

Fig. 4, fandl isl normally provided with base 14 and Va keyretainingarnr-15 suitx ably curved to press against the key 9 andretainit inv thefsheath 16 in locked posi-f tion.` `The base 14 of the spring 7 is suitably attached usually by means of solder to the desired object, and the downwardly projectingiianges 6k oftheoutershell'are v attached thereto overthe spring 7- inl similar fashion., The shell covering 12 isltelescoped over thekey` handlelO. Thekey 9 is inserted in the sheath 16 formed between the r outer shell 5 and outer surface of the object to which my invention vis attached, and is lreta-ined in, locked positionby the spring 7. As shown in Fig.'2,-the preferable'poly sition of the spring 7 lis to have its base 1.4 suitablyl soldered ort attached to the lob-kv ject near theopening of the sheath'16vanid to have its curved key-retaining arm 15` projecting inwardly so Aas yto properly lock the key,.when inserted in said sheath,v 16.

,As stated, my inventionl is peculiarlyV adapted tov a knife 1,' as the outer shell may be fashioned in ythe same shape ashthe upper` Vknife shell 3;;thebail member .4 extended to include both kthe knife proper i and the sheath; the exposedsurface of the outer. shell yand` the exposed surface of the key-handle shell covering k12 similarly ornamented; the base 14 of the' spring Tand Y the downwardly `projectingflanges 6 of thef.v`4

outer shell 5 suitably secured'tomthe outer` i 10.5y

knife shell 3;, thus forming avery neat,

compact and useful object with a kkey-retaining-'sheath 16 formed therein.,

Thezoperatio'n of my deviceis obvious L from the alcove description. When the key 9 is completely inserted in tlieisheatliY 16, the spring 'IT retains the key 9 in inserted position, the end of the shell casing l2 fitting flush against the end of the outer shell 5.

l lVhen it is desiredlto use the key 9, merely without wearing out.

pull out the casing 12 containing the key handle l0, and the spring 7 will give suinciently to permit of its withdrawal. As the spring 7is of compact metal'structure it is obvious that it will function indefinitely It is understood that my inventien is not liniitedr to the specific embodiment shown and that various deviations mayv be made therefrom without departing from the spirit and scope of the appended claims.

Vl/'hat I cla-im as newand desire to secure by Letters Patent is:`

l. An object-holding attachment, coniprising an outer shell casing, the outer edges thereof being provided with downwardly projecting flanges adapted to be attached to an object and to form a sheath between said shell casing and object, adapted to receive y 'anl object in said sheath, said second object Cil being provided with a handle and a shell covering on the exposed surface thereof, similar in form and of similar surface ornamentation to the outer shell casing, a spring provided with a base for attachment to the vdesired object near vthe opening of said sheath, and an integral curved arm thereof projecting inwardly of said sheath, adapted when the second object is inserted therein to retain said second object in locked position, the object handle and shell coverino thereof remaining exterior rof said sheatn and Aforming an exposed ornamented surface flush'with the outer surface of said shell casing.

2. An object-holding attachment, com-- prising an outer shell casing, the outer edges thereof being provided with downwardly projecting flanges adapted to be attached to the desired object land to form aV sheath between said shell casing and object, adapted to receive an object in said sheath, said second object being provided with a handle and a shell covering on the exposed surface thereof, a spring attached to the desired object underneath said shell casing, adapted when the second object is inserted to retain said second object in locked position, the object handle and shell covering thereof remaining exterior of said sheath and forming an exposed surface flush withthe outer surface of said shell y casing.

3. An object-holding attachment, comprising' an outer shell casing, the outer edges thereof being provided with downwardly projecting flanges adapted to'be attached to the desired object and to form a sheath between said shell casing and object adapted to receive an object therein, said second object being provided with a handle and a shell covering onk the exposed surface thereof, andmeans to retain the second object within said shell casing when inserted therein, the object'liandle and shell covering thereof remaining exterior of said sheath and forming an exposed surface flush withnthe outer surface of said shell casing.

4.7;As a new article of manufacture, a

6. As a new article of manufacture, a key-holding attachment for a knife, comprising an outer shell casing fashioned in similar shape to the knife shell, the out-er edges thereof being provided with downward projecting flanges adapted to telescope the edges of the knife shell and to be attached thereto and to form a sheath between said outer shell casing and knife shell adapted to receive a key therein, said key being provided with a handle and a 5 shell covering on the exposed surface thereof, and means to retain said key Within said sheath in locked position when inserted therein,y the key handle and shell covering. thereof remaining exterior of said sheath 4 and forming an exposed surface flush With 10 the outer rsurface of said shell casing.

In testimony whereof I aiX my signature.
